a major subclass of crustaceans

crustaceans characteristically having five pairs of locomotor appendages each joined to a segment of the thorax

typical crabs

a kind of crustacean

aquatic crustaceans typically having a carapace and many pairs of leaflike appendages used for swimming as well as respiration and feeding

minute marine or freshwater crustaceans usually having six pairs of limbs on the thorax; some abundant in plankton and others parasitic on fish

tiny marine and freshwater crustaceans with a shrimp-like body enclosed in a bivalve shell

marine crustaceans with feathery food-catching appendages; free-swimming as larvae; as adults form a hard shell and live attached to submerged surfaces

decapod having eyes on short stalks and a broad flattened carapace with a small abdomen folded under the thorax and pincers

any of several edible marine crustaceans of the families Homaridae and Nephropsidae and Palinuridae

small freshwater decapod crustacean that resembles a lobster

small soft-bodied marine crustaceans living in cast-off shells of gastropods

small slender-bodied chiefly marine decapod crustaceans with a long tail and single pair of pincers; many species are edible

shrimp-like decapod crustacean having two pairs of pincers; most are edible

edible tropical and warm-water prawn

shrimp-like planktonic crustaceans; major source of food for e.g. baleen whales

shrimp-like crustaceans whose females carry eggs and young in a pouch between the legs

tropical marine burrowing crustaceans with large grasping appendages

any of various small terrestrial or aquatic crustaceans with seven pairs of legs adapted for crawling

a kind of malacostracan crustacean

minute freshwater crustacean having a round body enclosed in a transparent shell; moves about like a flea by means of hairy branched antennae

small freshwater branchiopod having a transparent body with many appendages; swims on its back

common to saline lakes

a kind of branchiopod crustacean

minute crustaceans forming food for right whales

minute free-swimming freshwater copepod having a large median eye and pear-shaped body and long antennae used in swimming; important in some food chains and as intermediate hosts of parasitic worms that affect man e.g. Guinea worms

a kind of copepod
